Hey folks, we are exploring migrating from parquet/iceberg/hudi to delta. https://docs.databricks.com/ingestion/clone-parquet.html is this like “zero copy cloning”? does the CLONE command need to be only issued once?

When you clone, it creates a snapshot at that time. You can think of it as a fork that creates a new branch. If you clone and change the original table, the clone won’t also change. Deep clones copies the data files, shallow clone doesn’t copy the data files. https://www.databricks.com/blog/2020/09/15/easily-clone-your-delta-lake-for-testing-sharing-and-ml-reproducibility.html
